How to act when stuck in cash embezzlement case with my company?

Dears

Please note I am stuck in a cash embezzlement case with my company for 44k and I made a written confession about this and will return the amount.

My cheque and passport are on hold with the company. One more colleague of mine is involved in this case and he confessed for 204,000.

If he doesn't pay, will that affect my agreement?

Can the company retract the agreement and case against me?

I made some payments to the company and I have the proof of payments. Now the company wants to audit the amount.

If there's any difference, they will ask me to sign a new contract which I don't want to because I have not taken that amount.

If the other colleague who is involved also doesn't accept.the difference amount, what will be the scenario?

Please advise
